Important Significance

The real-time capacity-increase technology of transmission lines is adopted to increase transmission current capacity of transmission lines, by which the conductor temperature, the ambient temperature and the wind speed can be timely measured and the transmission current capacity can be adjusted dynamically without breach of available rules. A new type of Morgan's transmission line dynamic capacity-increase model is established, which can fast and effective computing the current line transmission capacity, and the transient running formula of transmission lines is established, the mathematical relationship between the conductor allowable temperature and the variety of sag of the span is presented, and the application of the monitoring device is introduced, it has important significance to research the power grid transmission interface dynamic capacity-increase technology.
